The object of my invention is to provide My invention. relates to a cooling system a simple and efiicient means torlthe 'circu1a-.

tion of air through refrigerating coils and A further object of my invention is. to provide a means separating the -fan from the ice covered coils in such a way thatthe accumulation of water will not'bedorced through the ducts.

A still further object of my invention is to provide a fan chamber having a means for modifying the thrust of the current uponv the cooling coils when greater force is re-j f quired to eject the air through the ducts, by which arrangement excess pressure upon the coils would tend to melt theice therefrom.

A still further object of my invention is to provide bafiie plates to control the direction of the current as it leaves the ducts.

A still further. object of my invention is to provide a fan chamber having a duct connected therewith to which tributaries may be attachedv and each'thereof having a separate controlling means.

A still further object of my invention is to provide a cooling apparatus applicable to public and private use, and may be thermostatically controlled, the said cooling apparatus having in co-operation therewith an electric motor, refrigeration plant and a thermostatic controlling means for theair circulating means. p

j proximity to the exit of the chamber as at .1 A. The duct 3 has a pair of battle lates 5 "horizontally pivoted as at B, the se ected angle of the plates being controlled by a crank 6 having a protrusion as at 7 to engage with a notched sector 8, by which means a selected angle-of the plates may be retained. On theend of the said duct are two vertically positioned battle plates 9 adapted to swing outward-for varying the flow of the current to the right or left as desired. "The said baffle plates Having a similar detent means for retainin the angle as above described. The duct 4' has a similar plate controlling means not shown in the drawings where the duct 4 connectsto the under side of duct 8 is a ba-fiie plate 10 functioning as a valve by which means the duct t may be closed, or 0 on to receive a desired force of current.- T e said ducts may be constructed of sheet metal, wood or composition, also the walls of thefan chamber.

The fan chamber is preferably mounted on a base 11 as means for spacing said chamber from the floor-so that a duct.ma y be extended rearward running between the chamher and the floor as shown in Fig. 1.

Rotatably positioned within said. chamber .is a fan 12 having curved wings as shown in Fig. 1, the said fan being trunnioned onbars 13 which are rigidly attached to their respective ends of the chamber. Concentrically positioned to the journal of the fan and each side of the chamber are valves 14 rotatably mounted, said valves adapted to close the air inlet for the fan oropen to any '1 portion desired, b which means the current ejected through t e ducts by the fan may be controlled. The current may also be controlled by thermostatic means acting on the motor 15 functioning as motive power for the fan. The -motor being diagrammatically shown in .Fig. 3 transmits power throu h the medium of a belt 16 to a sheave 17 w ich is rigidly attached to the fan journal.

Intermediately ositioned between the peripheral walls 0 the fan chamber and a lining 18 are a series of coils 2 extending from one side to the other as shown in Fig.

doubling the walls and placing a fibrous in- 3. The return bends of the coil being rigby which means the said machine clrculates the fluid through the coils. It being understood that the machine has the capacity of compressing and condensing such fluids as are commonly used for refrigerating purposes. By this system accumulation of coils and having ample space around the ice covered pipes, the air is free to circulate through what I will now term as a cooling chamber. The pipes thus covered by the ice have a greater surface exposure than would be by a continuous uninterrupted surface peripherall positioned. As a'modifying means for t e current from the fan I have provided an annular lining separating the fan from the coils and in said lining I have provided a series of apertures or de fiectors 22 placed in rows'across the lining. The said deflectors being staggered and in close proximity similar to t at shown in Fig. 4, the said deflector being formed by cutting the metal to a length as shown at C then by pressingroutward at one side of the cut as shown in igs. 1, 4, and 5, an opening is made through which air will flow as shown by arrows in said figures.

It is now readily seen how the air blast from the, fan is modified and distributed about the coils discharged therefrom anv ice will form on the,

as indicated by the arrows entering the ducts in' Fig. 1.

Such other modifications may be employed as lie within the scope of the appended claims.

Having thus described my invention,

what I claim as new and desire to secure 4 lar chamber for external discharge, a fan concentrically mounted to said annular cooling chamber, an adjustable intake valve for. the fan, a duct connecting to the fan I chamber, and a duct connecting to the first.

said duct in close proximity to the exit of the fan chamber, a valve for last said duct, said valve having a sector positioning means for the adjustment thereof, all substantially as shown and described.

2. In an air cooling apparatus, a fan chamber comprising a cooling compartment, a plurality of pipes connected by return bends for a continuous flow of refrigerating fluid, a fan and an apertured lining separating the fan from the coils as a retarding and distributing element for the current about said coils, an adjustable airintake for the fan, an air exit through the apertured lining, and an exit for the air cir-' culating around said through a duct.
